The Superoots Air Pot is a recyclable, reusable plastic container that actively enhances the quality of the root systems of plants. This revolutionary approach to containerizing plants and trees produces fabulous, non-spiraling root systems that are impossible to develop in any other available container. Made of recycled HDPE in the UK, the Superoots Air-Pot is circular in shape with a perforated sidewall. There are no flat surfaces due to the inward and outward pointed cones, which eliminates any chance of starting the spiraling process as well as dramatically increases growth rates. Air-Pot benefits: Eliminates root circling Reduces growing time in the garden Increases yields Simplifies production Minimizes the need to transplant Ensures Superior Performance in Extremes of Weather The Air-Pot is made of recycled HDPE plastic Reduces the chance for overwatering
